1. An information processing system, comprising:
a memory configured to:
store user information related to a user; and
store personality information that defines a personality unique to an agent, wherein
the personality information includes individuality information that defines individuality of the agent,
the personality information is based on one of a character in a real space or an animated character, and
the personality information is learned by a machine learning algorithm using learning data associated with the personality of the agent; and
a processor configured to:
determine the personality information is to be updated based on a growth stage of the personality of the agent;
acquire new learning data based on the determination that the personality information is to be updated, wherein
the new learning data includes a first set of phrases related to an adolescent stage of the agent in a case where the personality information is associated with a childhood stage of the agent, and
the new learning data includes a second set of phrases related to an adulthood stage of the agent in a case where the personality information is associated with the adolescent stage of the agent;
control the machine learning algorithm to relearn the personality information using the new learning data to update the personality information;
generate a behavior candidate based on the updated personality information and the user information, wherein
the behavior candidate is a candidate of an externalized behavior of the agent, and
the behavior candidate includes an utterance candidate of a plurality of utterance candidates;
calculate a matching degree between a content of the utterance candidate and the individuality information;
select the utterance candidate from the plurality of utterance candidates that has the calculated matching degree higher than a threshold;
transmit information indicating the selected utterance candidate to a user terminal; and
control the user terminal to output the selected utterance candidate as the externalized behavior of the agent.
